Cleanup of Old Services

I went through each of the services and checked the sites and webhooks for the given service. I removed ones that seemed to be gone, inactive, have issues, or simply not be working. I chose the safe side when I was unsure, so there may be more that can still be cleaned out.

I also fixed the permission to make the perms uniform across the folder.

However, I may have made a mistake or two, so for any of the files where there was a username written, here's a mention:

 - @jonbonazza - devaria;
 - @namebot - namecast;
 - @solanolabs - tddium;

---

Reply below if any of the removed webhooks should remain and I'll restore the file.
